L. Chmielarz et al., Pillared smectite modified with carbon and manganese as catalyst for SCR of NOx with NH3. Part I. General characterization and catalyst screening, CATAL LETT, 68(1-2), 2000, pp. 95-100
Carbon- and manganese-modified zirconia-pillared smectites were prepared, c
haracterized (XRD, BET and pore analysis, XPS) and tested in selective cata
lytic reduction of NOx with NH3. Both untreated and acidic pretreated smect
ites were used. The acid pretreatment increased NO conversion and influence
d the extent of carbon introduction into the porous system. The carbon depo
sit improved selectivity of the catalytic reduction to N-2.
